can i dissconect old internal HDD with vista on it & then Install New Internal HDD Put PC on, Then install vista via a DVD After Vista Has installed,What would happen if i connect the old HDD with the new HDD both with vista installed on it would i be able to access the data on the old HDD or would i have to format it
There's no issue with installing the Vista on the new HDD with the old one disconnected. That would be recommended. The issue would be that you can only have one Vista activated with your key, so the Vista on the old HDD needs to be deleted.
How much free space do you have on the old HDD?
Would it be enough free space to create another partition on it large enough to move the data to, so that you would be able to delete the old Vista installation and still have your data?
Post a screenshot of your Disk Management. Maybe we can work something out. And how big is your new HDD going to be and do you have an external enclosure.
If the latter were the case, you could define an empty Vista partition and an empty data partition on your new drive. Then move the data to the new data partition. From there you can delete everything on the old drive and reinstall into the newly defined Vista partition on the new drive.
I don't understand. I have an OEM version of Vista. It is installed on one partition of a relatively new hard drive and on two partitions of another hard drive. Both hard drives are connected to the SATA bus of one computer. Whenever I boot from one hard drive, I can access the other hard drive and all it's files. In fact, I use the hard drive that has two versions of Vista on it as my backup drive.
